Blair was coming for a few hours at the invitation of President Lech Kaczynski and was also to meet his twin brother, Prime Minister Jaroslaw Kaczynski who leads a socially conservative coalition government.

The leaders were also to discuss the military missions that both nations have in Iraq and in Afghanistan, as well as the situation of hundreds of thousands of Poles working in Britain, which opened its job market after Poland joined the EU in 2004.

Many countries, including Britain and Poland, want to strip down the current draft text and scrap certain parts, notably the charter's name, which for many suggests the creation of a European super state.
